T 0' all whom it may concern:

Be it known that I, GUino G. Bar-IN, citizen of the United States, residing at Detroit, county f lVayne, State of lvlichigan, have invented a certain new and Improved Method of Making Hood Hinges for Auto mobiles, of which the following is a specification, reference being had thereln to the accompanying drawings.

My invention relates particularly to a method of making hood-hinges for automobiles, althoughit may be capable of use for other purposes.

As is well understood by those skilled in the manufacture of automobiles, ditliculty has been experienced in the past in producing a hood-hinge WlllCll'Wlll withstand'the rough use to which it is subjected and Wlll not render the hood unsightly. Since the hood is at all times directly in front of the driver's eye and is a part of the car to which attention is usually first directed, it is most important that it shall have a neat and pleasing appearance. Heretofore, it has been customary to use a line of rivets or a series of spot-welds parallel with the pintle of the hinge to secure the hinge to the adjacent parts of the hood, and these have inter fered with finishing the hood, since the rivet heads project, and the spot-welding leaves indentations or spots where the enamel does not adhere well.

My present invention obviates both of these objections and leaves a hood the entire surface of which is unobstructed and can be perfectly finished.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings, and the novel features thereof will be pointed out and clearly defined in the claims at the close of this specification.

In the drawings, Fig. 1 is a side elevation of the hood of an automobile to which my invention is applied.

Fig. 2 is a section on line 2 of Figure 1.

Fig. 3 is a section of one hinge member ready to be secured to the hood.

Fig. 4 shows the hood and hinge member secured together. 7

Fig. 5 shows the parts shown in Figure "l completed and ready to be assembled.

smile as shown in Figure 3 to form one hinge member. As will be seen, this hinge member 11 is somewhat U-shaped in cross section, having two legs a and Z) which collectively constitute the leaf portion of the hin e, and a cylindrical or tubular portion 0, which is interrupted at intervals in the well-known manner. hen the parts are 9.SSG11'll)l(l, the tubular portion receives the pintle 1:2. One hood member 13 is then bentto an angle to form a flan e d along its edge, as shown in Figure 4, and it is then superposed in proper position on the hinge memher with the flange (Z in contact with the leg 6 of the hinge member. The parts are then secured together in whatever manner is most convenient, as for instance, by spotwelding or riveting.

In the drawings, I have shown spot-welding at the points 14, 1 1. Spot-welding is convenient because it does not require any punching operation and secures both legs of the hinge and the flange of the hood together at a single operation. The parts are then in the position shown in Figure 1. Thereafter, the flange d of the hood member13 is bent by rolling or otherwise to the position shown in Figure 5 in which the surfaces are practically in contact with each other and as nearly parallel as the nature of the material will permit.

The other hood member 15 and hinge member 16 are similarly constructed and secured together and the two hood members assembled by the insertion of the pintle 12.

hen completed, the exterior surface of the hood is left entirely smooth and is not marred by any spot-welding or rivet heads, so that the enamel or paint can be applied uniformly to its entire surface and its surface can be rubbed and polished with per feet ease.

The hinge produced by the method above described forms the subject matter of a prior application filed July 3, 1920, Serial No. 393,797, of which this case is a division.

What I claim is- 1. The method of hinging automobile hood members and the like which consist-s in providing a hinge member having a tubular pintle receiving portion and a leaf portion, securing an edge portion of a hood member to the outer side of the leaf portion of said hinge member, and then folding said hood member upon itself along a line parallel With and adjacent to the tubular portion of said hinge member.

2. The method of hinging automobile hood members and the like which consists in forming U-shaped hinge members, secur- 0 ing each hood member to the appropriate hinge member, and then folding the hood member upon itself along a line parallel With and adjacent to the folded edge of the Li-shaped hinge member so that the junction l5 between said two members is concealed.

In testimony whereof I affix my signature.
